SPECIFICATION forming part of Letters Patent No. 587,958, dated August 10, 1897. Application filed May 6, 1896. Serial No. 590,409. (No model.)

To all 10/007721 it Duty concern.-

Be it known that l, HENRY GREY, of Duluth, St. Louis county, Minnesota, have invented certain new and useful Improvements in Apparatus for Rollingllletallic Beams, Columns, Girders, &c.; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in apparatus for rolling metallic beams, girders, or columns, and comprises, primarily, a pair of suitably-rotated parallel rolls arranged horizontally, one above the other, and in the same vertical plane and adapted to roll the web and inner sides of the heads or flanges of the column, beam, or girder, and a pair of upright rolls arranged centrally between the axes of the two horizontally-a1 ranged rolls and at opposite ends, respectively, of the horizontal rolls and adapted to roll the outer sides of the flanges or heads'of the column, beam, or girder, in combination with simple and reliable means for driving the upright rolls in unison with the horizontal rolls and compelling the upright rolls to participate in the feeding of the work between the rolls.

My invention involves also an apparatus of the character indicated that comprises, in addition to the system of rolls for rolling the web and opposite sides of the heads or flanges of the work, another system of rolls arranged to roll the edges of the works flanges or heads and arranged, furthermore, sufflciently near to the first-mentioned system of rolls to cause the blank or work to be operated upon by either one of said roll systems before it has left the other roll system, and suitable driving machinery for operating both of said roll systems in unison.

My invention consists also in certain novel and meritorious features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a top plan, partly broken away, of two sys toms of rolls suitably arranged in the required proximity to each other and the ma chinery employed for causing the rolling or operating surfaces of the rolls of both roll systems to be driven at the same speed and in the required direction. Fig. 2 is a side elevation of the system of rolls employed in rolling the edges of the column, beam, or girder. Fig. 3 is a vertical section on line 3 3, Fig. 1, looking in the direction of the arrow. Fig. at is a side elevation of the system of rolls and appurtenances employed in rolling the web and opposite sides of the heads or flanges of the column, beam, or girder. Portions are broken away and in section in this figure to more clearly show the construction. Fig. 5 is a top plan, and portions are removed and broken away and in section in this figure to more clearly show the construction. Fig. 6 is a vertical section on each of lines 6 6, Figs. 4 and 5, lookingin the direction of the arrow. Fig. 7 is an enlarged side elevation of adjacent portions of the pair of horizontal rolls B B and a side elevation, mostiy in central vertical section, of the two upright rolls and appurtenances arranged at opposite ends, respectively, of said horizontal rolls, and exhibits also the operative connection employed between said upright rolls and the horizontal rolls. Fig. 8 is a top plan in horizontal section on line 8 8, Fig. 7.

Myimproved apparatus for rolling columns, beams, or girders, as illustrated in Fig. 1, comprises two systems of rolls one roll system, A, for rolling the edges of the heads or flanges of the column, beam, or girder, and the other roll system, B, for rolling opposite sides of the flanges or heads and the web of the girder, beam, or column. The two roll systems A and B are located side by side and in such proximity to each other that the work can be fed from the one system to the other, and the work, in feeding it from the one to the other roll system, shall be received by the latter before it has left the former, and the rolling or operating surfaces of the rolls of both systems of rolls are driven, preferably, at the same speed, and the work is fed in opposite directions, alternately, between and through the two roll systems as many times as required to complete the rolling of the work. The rolls of the two sys tems of rolls are of course rotated in thedirection required to feed the work and the direction of their rotation is of course reversed preparatory to feeding the work in the opposite direction after the latter has been fed in either direction through the systems of rolls. The roll system A, employed for rolling the edges of the heads or flanges of the beam, girder, or column, comprises two pairs of parallel horizontal rolls. (See Figs. 1, 2, and 3.) A designates the rolls of one of said pairs of rolls, and A represents the rolls of the other pair of rolls. The two pairs of corresponding rolls are arranged a suitable distance apart, and the rolls of each pair of rolls are arranged one below the other and in the same vertical plane. The upper rolls of the two pairs of rolls areoperatively mounted upon or connected with a horizontal shaft A that is adjustable vertically and has bearing in half-boxes A, movable up and do wn within the two upright housings A and resting upon or supported from any suitable number-of upright bars Afloperatively connected at their lower ends with vertically-tilting weighted levers A whose weights A somewhat more than counterbalance the weight of shaft A and the rolls upon said shaft and act in the direction required to elevate said rolls. Saddles or blocks A rest upon shaft A above half-boxes A and suitably-operated screws A engage correspondingly-threaded holes in the tops of the housings and engage the up per surfaces of saddles A and limit the upward movement of shaft A and the rolls upon said shaft. Means or mechanism of the character indicated for adjusting a horizontal roll vertically and retaining it at the desired elevation are well understood by those skilled in the art and do not require further description in this specification. Suffice it to state that screws A should be uniformly operated and that the upper rolls are elevated or lowered according as said screws are turned in the one direction or the other. The two upper rolls are confined upon shaft A between the different housings A A respectively, and a collar A formed upon said shaft centrally between the two housings. The two lower rolls are operatively mounted upon or connected with a horizontal shaft A suitably supported from housings A and said lower rolls are confined upon said shaft A between the different housings, respectively, and an annular collar A formed upon the shaft centrally between the housings.

Although I have illustrated rollsadapted for the production of I-beams or girders, I would have it understood that the principle of my invention is not merely applicable to the rolling of this particular form of beam or work. The suitably-heated blank or I-beam or work 0 in the case illustrated is of course fed longitudinally and with its flanges or heads arranged edgewise between the upper and lower rolls of the pairs of rolls A A and the two flanges or heads of the blank or work areoperated upon by the different pairs of rolls,"respectively, and the two rolls of each pair of-. rolls operate upon opposite edges, re-

spectively, of the respective flange. A and A are larger diametrically than the rolls, but are narrower than the web of the work-constituting beam and are not sufliciently large diametrically to make contact with or operate upon the web. In other words, collars A and A merely serve as lateral guides for the work during the rolling operationand effectually prevent displacement of the work laterally during the said operation, and the upper rolls can be readjusted vertically after each pass of the work to accommodate the widening of the heads or flanges of the work during the preceding pass.

Shaft A (see Fig. 2) is operatively connected, by means of suitable couplings or connections A with a suitably-supported horizontally-arranged shaft (1, and shaft A is operatively connected, by means of suitable couplings or connections A ,with a horizontal shaft a, arranged above and parallel with shaft a. Two, spur gears a a operatively mounted upon shafts a and a, respectively, and having a corresponding number of teeth, mesh with each other, and gear a meshes with Collars a driving-pinion a operatively connected in any approved manner with a suitably-supported and suitably-actuated driving-shaft a. By the construction thus far described it will be observed that the rolls of each pair of rolls A and A are driven in oppositedirections, respectively, as required.

Another pinion a (see Fig. 1) is operatively mounted upon driving-shaft a and meshes withas urearct o erativel mountedu on A a horizontal shaft a suitably supported at one side of and a suitable distance from shaft a and operatively connected, by means of suitable couplings or connections a with a spurgear a arranged in line with shaft a and between said shaft a and the trunnion I) (see Fig. 1) of the lower roll B of the pair of parallel corresponding horizontal rolls B B arranged one above the other in the same vertical plane and parallel with rolls A A and employed in rolling the web and the inner side of the heads or flanges of the beam that is being rolled, and any suitable couplin gs or connections establish operative connection between said trunnion b and gear a A spur-gear a is arran gcd above and parallel B and the lower roll B are driven in the same direction as the upper rolls and lower rolls,

respectively, of the two pairs of rolls A and hence the work can be fed from rolls A the driving-shaft is actuated in the one direction or the other, and the two systems of rolls are arranged in sufficiently close proximity to each other to enable the one system of rolls, as already indicated, to operate upon the work before the latter has left the other roll system. Of course rolls B B are arranged in line with collars A and A respectively, of shafts A and A but said rolls B B are sufficiently wider and diametricallylarger than said collars to enable them to properly operate upon the web and the inner sides of the flanges of the beam that is being rolled. The upper roll B is of course adapted to operate upon the upper side of :the web and adjacent inner surfaces of the heads or flanges of the beam, and the lower roll B is adapted to operate upon the lower side of said web and the adjacent inner surfaces of said heads or flanges.

Anysuitable number of suitably-supported horizontally-arranged rolls 0 (shown in Fig. 1 only) are preferably arranged between the two systems of rolls in position to afford a bearing for the beam or work in the passage of the latter from the one to the other system of rolls. I

Two suitably-s11 pported side rolls D and D, shown arranged vertically at opposite ends, respectively, of the horizontal rolls B B and centrally between the axes of said horizontal rolls, (see Figs. 4, 5, 7, and 8,) are adapted to roll or operate upon the outer sides of the oppositely-located flanges or heads, respectively, of the beam. It is obvious that in order to accommodate repeated rollings of the work and different sizes of work the upper roll B must be adjustable vertically and the two upright rolls D and D must be adj usta-ble apart.

Before referring to the mechanism employed for effecting the adjustment of said adjustable rolls I would remark that in order to render the rolling of a flanged beam, column, or girder practicable live surfaces should be presented to all sides of the work, and consequently the upright rolls for rolling the outer sides of the flanges must be driven in unison with the horizontal rolls B B and the very simple and durable operative connection I have devised between each of said upright rolls and the adjacent trunnion of the upper horizontal roll B comprises, preferably, a horizontal friction wheel or disk d, (see Figs. 4, 6, 7, and 8,) operatively connected with the respective upright roll in any approved manner and preferably by the formation of interlocking lugs 61 and D upon said friction-wheel and the roll, respectively. The upright roll is bored centrally, as at D*, (see Fig. 7,) and the lugs D are formed upon the upper portion of the surrounding wall of said bore. (8% also Fig. 8.) The friction-wheel is therefore arranged within or extends into the upper portion of the bore through the roll, and the aforesaid interlocking lugs are arranged vertically to accommodate an up-and-down movement or adjustment of the frictionwheel for the purpose hereinafter made more apparent. Said friction-wheel d at its upper end is provided with an external annular beveled or conical friction-surface (P, that is frictionally engaged by a corresponding annular beveled or conical friction wheel or disk B formed upon or operatively connected with the adjacent trunnion of the upper horizontal roll B. j

The two friction-disks B are reversely arranged and engage the inner or oppositelylocated extremities, respectively, of the different friction wheels or disks cl cl, respectively, so that the two uprightside rolls D D shall be driven in opposite directions and in the direction necessary to render said upright rolls instrumental, as required, in feeding the work between them and between the horizontal rolls. It is obvious that all of the live surfaces operating upon the work should be driven at the same speed, and hence the relative diameters of wheels cl and the connected rolls D D are so proportioned to the relative diameters of disks B on rolls B B that the rolling or operating surfaces of all of said rolls shall be driven at the same speed, or nearly so. Friction-disks B are preferably removably mounted upon the supporting rolltrunnions to accommodate their use with any size of rolls employed in rolling theweb of the blank or work. By means of the vertical adj ustability of disks cl frictional engagement is maintained between said friction members and the friction-disks B upon elevating or vertically readjust-ing the upper horizontal roll 13.

The means acting to elevate each frictiondisk cl and maintain frictional engagement between said friction member and the engaging friction-disk B comprises, preferably, a piston E, provided at or near its upperend with an external annular flange E, that engages the under side of and supports member d, that is secured to'the piston preferably by a nut 6, (see Fig. 7,) mounted at the upper side of said member 61 upon an externallyscrew-threaded upright lug e of the piston and extending upwardly through the central portion of said member d. The piston extends downwardly into the chamber f, formed in the vertical cylindrical lug or cylinder F, formed upon the upper side of a block F, and upon said cylinder the upright roll that is operatively connected with the aforesaid friction-disk d; is mounted. Block F at the lower end of cylinder or bearing F is pro- 7 vided with a horizontal annular shoulder F (see Fig. 7,) and antifriction-balls F are interposed between said shoulder and the lower end of the roll and reduce the friction had between the opposing surfaces of said roll and shoulder during the operation of the roll to a minimum. A port or passage-way f for conducting water or fluid under pressure to chamber f is formed in any approved manner within block F and communicates with the aforesaid chamber. The fluid under pressure within said chamber acts to force the piston upwardly, and thereby causes the horizontal friction-disk d to be held in frictional contact with the engaging friction-disk B A stufling-box F is provided around the, piston at and supported by the upper end of cylinder F and prevents upward leakage of the fluid under pressure from chamber f. Block F straddles but does not rest upon the adjacent trunnion of the lower horizontal roll B as shown in Figs. 4, 6, and 7. Said roll B has its trunnions suit-ably supported within the lower ends of the two upright housings G G, arrranged at opposite ends, respectively,

of rolls B B and said block F rests upon horizontal shoulders g, formed upon the opposing internal walls of the adjacent housing. (See Fig. 6.) Blocks F slide upon shoulders during the adjustment of the two upright I rolls D and D toward and from each other.

' projecting brackets G, having tongues G engaged by the grooves 72 (see Figs. 4 and 5,) formed in a slide H-that is, two horizontally-movable slides H H are arranged at the outer sides of the difierent housings, respectively, and each roll-bearing block F is rigidly secured'to the adjacent slide H by any suitable number of bolts H, extending through the slide into said block F, as shown in Fig. 5, and hence the upright roll borne by said block F is adjusted toward or from its companion roll according as slide H is moved laterally of the supporting-housing in the one direction or the other. Each slide H is pro vided, preferably, with two screws H arranged parallel with the slideways for said slide and a suitable distance apart and operatively connecting with the slide in any approved nianner. Said screws engage correspondingly-threaded nuts I, confined or tendered stationary within recesses g, formed in the outer sides of the aforesaid housingbrackets, as shown in Fig. 5. By this construction it is obvious thateach slide H and the members supported thereby are adjusted toward or from the pair of horizontal rolls according as the engaging screws are turned in the one direction or the other.

Housings G are preferably tied togetherand braced apart by any suitable number of suitably-applied horizontally-arranged rods G Each slide H is also'provided with a thrustbearing for the upright roll that is indirectly supported from said slide, and said thrustbearing consists, preferably, of a segmental plate J, (see Figs. 5, 7, and 8,) composed of very hard metal or material and supported on edge from the slide at that side of the roll that Y is opposite to the point at which the roll operates upon the work. Said thrust-plate is furthermore arranged concentrically of the axis of the roll, and any suitable number of suitably-supported upright antifriction-rollers J are preferably interposed between the thrustplate and the roll to reduce the friction between the opposing surfaces of said plate and roll to a minimum. The port or passage-way f, formed within each block F, is arranged in line and communicates with a port or passageway h, that extends through the slide H, V

with which said block is operatively connected, and communicates at its outer end, preferably,with a flexible pipe or hose K, (See. Fig. 4,) that connects with any suitable source (not shown) for supplying the fluid under pressure, and by virtue of its flexibility accommodates the adjustment of said slide.

To prevent overheating of the mutuallyengaging friction-wheels d and B and the connected rolls, each chamber f communicates with a port 6 (see Fig. 7,) extending upwardly through the piston that extends into said chamber, and said port at its upper end terminates in a nozzle or nipple 6 arranged to discharge upwardly above the adjacent friction -wheel 01 and against the adjacent trunnion of the upper horizontal roll B, and the water or cooling agent spreads or circulates to the engaging surfaces between said frietion-wheels. The upper horizontal roll B is supported, preferably, exclusively from the fluid under pressure, and through themedium of pistons E, upon which said fluid acts, and the friction disks or wheels interposed between said pistons and the trunnions of said roll.

Two upright screws L L (see Figs. 4 and 6) engage correspondinglythreaded holes formed in the tops of housings G G, and are arranged to form stops that limit the upward movement or elevation of the upper horizontal roll B. Saddles Z are shown interposed between the lower ends of said screws and the trunnions of said roll.

By the construction hereinbefore described it is obvious that upon turning screws L in the direction required to elevate them the upper horizontal roll B will be elevated by the action of the fluid under adequate pressure upon pistons E.

Having described suitable means for obtaining the adjustment of the upright rolls D and D toward and from each other notonly to accommodate different sizes of work, but as required during the rolling of work of the character indicated, and having also described suitable means for eifecting a vertical adjustment of the upper horizontal roll .15 toward and from the lower horizontal roll 13? and indispensable in the process of doing work of the character indicated, I would re mark that it is also desirable to have the screws employed in effecting the vertical adjustment of said upper horizontal roll and the screws employed in eifecting the adjustment of the vertical or upright rolls D and D operatively connected with each other, I

and this is readily accomplished by means of the following well-known gearing and shafting: A bevel-gcar L'is operatively connected with the upper end of each screw L. A suitably-actuated horizontally-a1ranged shaft M is suitably supported from said screws, and two bevel-pinions M M, operati vel y mounted upon said shaft M, mesh with the correspon ding sides of the different bevel-gears L L, respectively. A bevel-gear 7L2 is operatively mounted upon the outer end of each screw H and meshes with a beveled pinion O, that is operatively mounted upon a suitablysupported upright shaft 0. A suitably-supported bevel-gear O is operatively and slidably mounted upon the upper end of each shaft 0 and meshes with a bevel-pinion M that is operatively and slidably mounted upon shaft M and provided with a vertically-arranged sleeve M slidably mounted upon a vertical upright H that is rigid with the slide H below.

Two pairs of horizontal guide-bars P (see Figs. 4, 5, and 6) are arranged at opposite sides, respectively, of and centrally between the axes of rolls B B and the bars of each pair of guide-bars are arranged at opposite sides, respectively, of the path of the work. Said bars prevent lateral displacement of the work during the feeding of the latter to and from the rolls. The members of each pair of guide-bars are adjustable apart and are secured in any approved manner, by means of rods P, to the different slides 11 H, respectively, and each of the guide-bars is seated near its inner end upon a shoulder F formed upon the block F, that is secured to the slide instrumental in supporting said bar, and said block is provided, preferably, with an upright lug or flange F bolted, as at F, to the guidebar. By this construction each guide-bar P is well supported at or near each end and is not liable to be bent laterally or buckled by the work.
